Legacy Machine 101 Frost / MB&F

The MB&F Legacy Machine 101 Frost gets its name from the antiquated (but remarkable) finishing style of 18th and 19th century pocket watch movements, known as frosting. This was initially done by treating the surfaces with an acid mixture and then heating them over an open flame. Wire brushing slowly replaced acid over the years, but introduced other concerns such as uniformity of finish. Brush finishing today is a closely guarded secret by the few craftsmen that wield the trade. This is more than evident in the new LM101. Its surfaces both recall and outdo the fine frosting of high-end vintage pocket pieces. The new diameter of the LM101 is 40 mm, which is quite the curtailing from the original 44 mm LM1. The MB&F Legacy Machine 101 Frost will be limited to 33 pieces in 18k red gold and 18 pieces in 18k yellow gold. Pricing for either will be US$64,000 — via HODINKEE
